Question

Why is sliding friction always less than the static friction

Answer 1

The sliding friction is less than static friction because of the interlocking of irregularities in the two surfaces. When the object starts sliding the contact points on its surface, do not get enough time to lock into the contact points on the floor. So the sliding friction is slightly less than the static friction.

Answer 2

Friction is a force that opposes the motion of an object.In slide friction...the object doesn't move...while in slide friction the object slide over one another....So static friction is more than sliding friction.

Hope this will help u
